702880f243 Add i915 ioctls to configure pipes for vblank interrupt.
i915 vblanks can be generated from either pipe a or b, however a disabled
pipe generates no interrupts. This change allows the X server to select
which pipe generates vblank interrupts.

f2a2279ffc drm: radeon add a tcl state flush before accessing tcl vector space
Do a tcl state flush before accessing tcl vector space. This fixes some
more problems with flickering (bug #6637). drm may not be appropriate
place for this, since doing that flush there might both be overkill and
insufficient in some cases. However, it's hard to figure out when that
flush is needed, so this has to suffice. There does not seem to be a
performance penalty associated with it.

Radeon driver.  Patch is attached.

I can't be sure about the "CHIP_RV350", I copied it from the X300 entry
(from http://dri.freedesktop.org/wiki/ATIRadeon, X600 is a rv380 chip while
X300 is a rv370).  But, at least it works now.

392c14beac Revert radeon AGP aperture offset changes
This reverts the series of commits

	67dbb4ea33
	281ab031a8
	47807ce381

that changed the GART VM start offset.  It fixed some machines, but
seems to continually interact badly with some X versions.

Quoth Ben Herrenschmidt:

  "So I think at this point, the best is that we keep the old bogus code
   that at least is consistent with the bug in the server. I'm working on a
   big patch to X that reworks the memory map stuff completely and fixes
   those issues on the server side, I'll do a DRM patch matching this X fix
   as well so that the memory map is only ever set in one place and with
   what I hope is a correct algorithm..."

67dbb4ea33 [PATCH] Fix more radeon GART start calculation cases
As reported by Jules Villard <jvillard@ens-lyon.fr> and some others, the
recent GART aperture start reconfiguration causes problems on some
setups.

What I _think_ might be happening is that the X server is also trying to
muck around with the card memory map and is forcing it back into a wrong
setting that also happens to no longer match what the DRM wants to do
and blows up.  There are bugs all over the place in that code (and still
some bugs in the DRM as well anyway).

This patch attempts to avoid that by using the largest of the 2 values,
which I think will cause it to behave as it used to for you and will
still fix the problem with machines that have an aperture size smaller
than the video memory.

ee219e5e7c [PATCH] radeon drm: fix compilation breakage with gcc 2.95.3
Fix a typo which breaks radeon drm compilation with gcc 2.95.3.

The offending line was added back in 2.6.11-rc3, but was harmless
back then. A recent addition nearby changed it into a compilation
breaker: commit 281ab031a8.

The doubled semi-colon ends up being an empty instruction, and the
variable declaration thus ends up being in the middle of "code".

281ab031a8 [PATCH] radeon drm: fix agp aperture map offset
This finally fixes the radeon memory mapping bug that was incorrectly
fixed by the previous patch.  This time, we use the actual vram size as
the size to calculate how far to move the AGP aperture from the
framebuffer in card's memory space.

If there are still issues with this patch, they are due to bugs in the X
driver that I'm working on fixing too.

47807ce381 [drm] fix radeon aperture issue
Ben noticed that on certain cards we've landed the AGP space on top of
the second aperture instead of after it..  Which messes things up a lot
on those machines.

This just moves the gart further out, a more correct fix is in the works
from Ben for after 2.6.15.

cf65f1623d drm: fix quiescent locking
A fix for a locking bug which is triggered when a client tries to lock with
flag DMA_QUIESCENT (typically the X server), but gets interrupted by a signal.
The locking IOCTL should then return an error, but if DMA_QUIESCENT succeeds
it returns 0, and the client falsely thinks it has the lock. In addition
The client waits for DMA_QUISCENT and possibly DMA_READY without having the lock.

22eae947bf drm: rename driver hooks more understandably
Rename the driver hooks in the DRM to something a little more understandable:
preinit         ->      load
postinit        ->      (removed)
presetup        ->      firstopen
postsetup       ->      (removed)
open_helper     ->      open
prerelease      ->      preclose
free_filp_priv  ->      postclose
pretakedown     ->      lastclose
postcleanup     ->      unload
release         ->      reclaim_buffers_locked
version         ->      (removed)

postinit and version were replaced with generic code in the Linux DRM (drivers
now set their version numbers and description in the driver structure, like on
BSD).  postsetup wasn't used at all.  Fixes the savage hooks for
initializing and tearing down mappings at the right times.  Testing involved at
least starting X, running glxgears, killing glxgears, exiting X, and repeating.

Tested on:      FreeBSD (g200, g400, r200, r128)

4e57b68178 [PATCH] fix missing includes
I recently picked up my older work to remove unnecessary #includes of
sched.h, starting from a patch by Dave Jones to not include sched.h
from module.h. This reduces the number of indirect includes of sched.h
by ~300. Another ~400 pointless direct includes can be removed after
this disentangling (patch to follow later).
However, quite a few indirect includes need to be fixed up for this.

In order to feed the patches through -mm with as little disturbance as
possible, I've split out the fixes I accumulated up to now (complete for
i386 and x86_64, more archs to follow later) and post them before the real
patch.  This way this large part of the patch is kept simple with only
adding #includes, and all hunks are independent of each other.  So if any
hunk rejects or gets in the way of other patches, just drop it.  My scripts
will pick it up again in the next round.
